Question

Найдите силу тока в участке цепи, если его сопротивление 50 Ом, а напряжение на его концах 5 В. Ответ выразите в миллиамперах.

Answer 1

Объяснение:

закон Ома на участке цепи это отношение напряжения к сопротивлению равно силе тока 5/50=0,1 ампер

или 10 милиампер

Answer 2

Calculating Current in the Circuit

To calculate the current in the circuit, we can use Ohm's law, which states that the current (I) flowing through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R) between them. The formula for Ohm's law is:

I = V / R

Where: - I = current in the circuit (in amperes) - V = voltage across the circuit (in volts) - R = resistance in the circuit (in ohms)

Given: - Resistance (R) = 50 ohms - Voltage (V) = 5 volts

Using the formula, we can calculate the current in the circuit:

I = 5 V / 50 Ω

I = 0.1 A

To express the current in milliamperes (mA), we can convert the result:

0.1 A = 100 mA

So, the current in the circuit is 100 milliamperes.
